The Xbox already has a number of stereoscopic 3D games, from Crysis 2 to Call of Duty: Black Ops. The upcoming announcement will centre on providing 3D at 720p resolution rather than the half-resolution approach used by these existing titles.

They pack the left- and right-eye images into a single 1280 x 720 frame. The new technique will render the 720p stereoscopic elements into a 1280 x 1470 frame.

Microsoft won't comment on rumours and speculation, but with Sony's 3D games receiving much appraisal, it's about time Microsoft followed suit. ®
